Aligning Gitab and Github plugins with Bitbucket

[shikari-ac]

This pull request introduces several significant enhancements and fixes to the VCS plugin's integration with GitLab and GitHub APIs. These updates improve functionality, add support for new features, and resolve existing issues.

Common Functionality Across GitLab and GitHub

The following functionalities have been aligned and supported for both GitLab and GitHub plugins:

• Listing organizations and repositories for GitHub and groups, subgroups, and projects for GitLab.
• Retrieve Pull/Merge Request Information.
• Add Role to a Pull/Merge Request: Supports adding users to a PR/MR as reviewers or assignees.
• Set Status of a Pull/Merge Request.
• Commenting on a particular PR/MR.
• Fetches repository/project code and changes associated with a PR/MR.

GitLab Plugin Enhancements

• Resolves projects across all sub-projects of a given group.
• Lists groups available for the current user, supporting the entire VCS scope.
• AddRoleToPR supports assignee and reviewer roles.
• SetStatusOfPR supports approve and unapprove statuses.
• File Upload and Markdown Commenting. Uploads files and constructs markdown comments with links to uploaded files.
• Library Migration: Moved from xanzy/go-gitlab to gitlab.com/gitlab-org/api/client-go due to deprecation of the former library.

GitHub Plugin Enhancements

• Lists all organizations accessible to the authenticated user if a user doesn't pass a namespace in args.
• AddRoleToPR supports assignee and reviewer roles.
• SetStatusOfPR supports approve and request_changes statuses. Approve status requires a comment, unlike other VCS providers.

Bitbucket Plugin Enhancements

Supported listing of users forks/repositories.

Custom HTTP Clients for VCS

VCS clients now support custom HTTP clients, which can be configured via the Scanio configuration file.
Custom headers are fully supported, providing enhanced flexibility.

VCS URL Parsing

• Introduced specialized parsers for GitLab and GitHub URL formats.
• Updated Bitbucket parsing to support listing user fork/repositories.

Go Version

Bump go version 1.19 -> 1.23

Fixes

Fixed incorrect argument validation for the list command, ensuring proper input handling.
